PENCIL.

SPECIFICATION forming part of Letters Patent No. 386,892, dated July 31,1888.

Application filed March 5, 1888. Serial No. 266,201. (No model.)

To aZZ whom, it may concern.-

Be it known that I, OSCAR MUssINAN, Jr., of the city, county, and Stateof New York, have invented a new and useful Improvement in Pencils; andthe following is declared to be a description of the same.

My invention relates to a pencil wherein a propel and repel action canbe given to the lead, so that the lead or other writing-point can beprojected for use or retracted when not in use.

I employ a tubular body or sheath for the movable lead or stylus, atubular end cap of metal adapted to fit over the tubular body, and afriction device between the end cap and lead or stylus, against whichdevice the cap,when in place upon the tubular body,exerts a compressingor squeezing pressure,which acts upon the lead or stylus to maintain itin a projected or retracted position. When the tubular body is graspedin the hand, the lead is propelled or projected by pressing the end capagainst a stationary object and forcing it farther upon the sheath, orthe lead or stylus is repelled by pressing its point against astationary body.

In the drawings, Figure 1 is an elevation and partial longitudinalsection of my improved pencil. Fig. 2 is an elevation of the end of thetubular body without the cap. Figs. 3 and 4 are elevations and partiallongitudinal. sections of modifications of my improvement, and Fig. 5 isan elevation of the end cap of Figs. 3 and 4.

a represents the tubular body or sheath, which in all cases becomes thehandle of the pencil, and the same is preferably made of wood, and thepoint is adapted to be cut away as the lead is used up to the wood,Figs. 1 and 3; but in the modification shown in Fig. 4 the same may bemade of hard rubber, celluloid, or similar material.

1) represents the removable lead, as shown in Figs. 1 and 3, and b themetal stylus shown in Fig. 4, such as traveling salesmen prefer toemploy for writing letters, 850., with manifold paper.

The end of the tubular body or sheath (1 is bored through transversely,as at 1, and slotted longitudinally from the top end to the hole 1, asat 2, (see Figs. 1, 2, and 4,) so that the divided end of the tubularbody is capable of being compressed to bring its two parts toward eachother. The slotted end of the tubular body, Figs. 1 and 2, is tapered onthe outside at 3 to the smaller parallel-sided end 4.

In Fig. 1 the tubular end cap of metal is made preferably in two parts,0 c, the parallel part c sliding within the tapering end of the part c.There is a stiffening-rib, 5, having a knurled edge formed in thetubular portion 0, and also a section of a screw-thread at 6. Thetubular portions 0 c are passed over the end of the tubular body a, andthe portion 0 is revolved slightly, to cause the screwsection 6 to screwupon the incline 3 and compress the parts of the slotted end toward eachother and produce a friction or binding action upon the lead or stylusto hold it in place.

In Fig. 3, e is a small piece of rubber placed between the lead b andtubular metal cap a in an opening made in the tubular body or sheath a,the said cap a compressing the rubber when the cap is slid upon the endof the pencil, the rubber acting as a friction against the lead orstylus.

The metal cap 0 is slotted, as shown in Figs. 3, 4, and 5, so as to actas a spring when pressed over the end of the tubular body or sheath, andcompress the rubber shown in Fig. 3, or compress the parts of theslotted end of the tubular body, Fig. 4, to produce a friction orbinding action upon the lead or stylus.

The lead or stylus is projected by grasping the tubular body in the handand pressing the end cap against a stationary object or against thefingers or hand, so as to move the cap and lead endwise and project suchlead. By pressure against the end of the lead in a similar manner it maybe moved into the case or body,the cap sliding back at the same time.

I claim as my invention- 1. The combination of the tubular body orsheath a, divided by a slot at one end, with a tubular metal end capthat is adapted to fit over the end of the divided portion of thetubular body and compress the same to cause I moving the lead endwise,substantially as set 10 a friction on the lead or stylus, substantiallyforth.

I as specified. Signed by me this 28th day of February,A.

The combination, with the tubular body D. 1888. or sheath a, slottedat one end, of a tubular portion, 0, adapted to fit over the end of thetubular body and to compress its divided end WVitnesses: to cause afriction on the lead, and the tubu- GEO.
